Questions in regards to stock uploads

I am new to adobe stock and have some questions about what causes my images to be rejected. I have submitted the exact same photos to other stock platforms as they were accepted while adobe stock keeps rejecting the images. Is adobe stock really strict like istock used to be? I understand that the image below has some out-of-focus bits but I believe that's part of what makes the photo work. Maybe I am wrong and need to learn how adobe stock works. Any help and critiques would be appreciated.
